RATIO (RATIO Architects)
The preservation architect that recurs most often on central Indiana landmarks: Washington County Courthouse, the Saarinen church tower in Columbus, Hinkle Fieldhouse at Butler (tuckpointing all the masonry and restoring the steel-sash windows), and the Indiana Soldiers' and Sailors' Monument. Its specialist Anne Schneider presented the masonry diagnosis at First Christian Church alongside ARSEE Engineers.

Our verification notes
Architect rather than contractor - the firm that writes the specification a mason then builds to. Four of its staff appear on the state DHPA roster with Section 106 and tax-credit service codes, which matters if the church is listed or is pursuing historic tax credits. Google Business Profile exists but carries no rating, recorded as empty rather than invented.
